HTC One 64GB developer edition priced at $649, ships April 19

Last month HTC announced the developer edition of the HTC One, which was priced at $649. Unlike the standard HTC One sold in the US, the developer edition would come only in 64GB capacity, will be carrier unlocked and will have an unlocked bootloader, a must of you plan on installing custom...

In a couple of months time nobody will even remember this stupid iPhone wannabe with its dodgy camera.
Next Xmas everyone will be laughing at the suckers who bought it, when all its competitors from Sony, Samsung, Huawei, etc. will be moved to Android 5.0, and around that time HTC starts to rollout the 4.2 update for the One.

I heard [seen in xda developers blog]that most of the pre-ordered HTC Ones are shipped with some manufacturing defects like some pretty worrying gaps on the corners and some even were able to remove the plates on the front side on top of the speakers. So at this point is it good to take this dev edition model? What if we want to wait for the dev's edition to be available in the market?
